Underground Storage Tanks

Owners and operators of Underground Storage Tank (UST) systems must cooperate fully with inspections, monitoring and testing conducted by the Environmental Protection Agency (EPA). Owners and operators are required to submit the following information:

1. Notification for all UST systems, which includes certification of installation for new UST systems;
2. Reports of all releases including suspected releases, spills and overfills and confirmed releases;
3. Corrective actions planned or taken, including initial abatement measures, initial site characterization, free product removal, investigation of soil and ground-water cleanup and corrective action plan; and
4. A notification before permanent closure or change-in-service.

Owners and operators must maintain the following information:

1. A corrosion expert’s analysis of site corrosion potential if corrosion protection equipment is not used;
2. Documentation of operation of corrosion protection equipment;
3. Documentation of UST system repairs;
4. Recent compliance with release detection requirements; and
5. Results of the site investigation conducted at permanent closure.

Owners and operators must keep the records required either at the UST site and immediately available for inspection, or at a readily available alternative site and be provided for inspection upon request. For at least three years after closing an UST, owners and operators must keep records of the site assessment results required for permanent closure and records that document their financial responsibility.
